    "abstract": "We analyze the propagation of a pair of quantized fields inside a medium of\nthree-level atoms in $\\Lambda$ configuration. We calculate the stationary\nquadrature noise spectrum of the field after propagating through the medium, in\nthe case where the probe field is in a squeezed state and the atoms show\nelectromagnetically induced transparency (EIT). We find an oscillatory transfer\nof the initial quantum properties between the probe and pump fields which is\nmost strongly pronounced when both fields have comparable Rabi frequencies.\nThis implies that the quantum state measured after propagation can be\ncompletely different from the initial state, even though the mean values of the\nfield are unaltered.",
